Patented Dec. 23., 1919.

i Application led July 30, 1918. Serial No. 247,419.

To all whom t may concern:

Ee it known that I, GEORGE F. WTELLS, a

n citizen of the United States, residing at Elyria, in the county ofLorain and State of Ohio, have invented certain new and usefulImprovements in Eubber Heels for Shoes,` of which the following is aspecification.

This invention relates to shoe heels and more particularly to rubberheels.

The primary object of this invention resides in the provision of a heelfor shoes consisting of an embodiment of elements for prolonging thewear of the heel and preventing the slipping of individuals on wet oroily pavements.

'With these and other objects in view this invention resides in certainnovel features of construction and arrangement of element hereinaftermore particularly set forth and pointed out in the appended claim, itbeing understood that the right is reserved to resort to any change inconstruction as comes within the scope of the claim.

ln the accompanying drawing Figure l is a bottom plan view of a rubberheel as constructed in accordance with this invention;

Fig. 2 is a longitudinal sectional view thereof on line 2- 2 of Fig. l;

F ig. is a cross sectional view thereof on line 3 3 of Fig. 1.

ln the present embodiment of this invention. the letter l-l designates arubber heel for shoes, boots or the like, which is provided with aconcave inner surface B to create a suction on the bottom of the shoeand a similarly formed surface C of greater depth connnunicatingtherewith for cushioning the weight of an individual having these heelson his shoes.

Embedded as by dove-tailing in the lower portion of the rubber heel is afelt plug 6 the lower surface of which is disposed in a planesubstantially in alinement with that upon which the lower edge of theheel lies.

This felt plug is provided along its edges with inwardly directedrecesses which have their innermost walls 8 of areual formation anditsside walls 9 extended obliquely `inward to form doveetail pockets forthe re cept-ion of rubber tongues 10 of a similar shape. Formed in thecentral portion of this felt plug is an aperture lil for the receptionof a rubber lug 12 formed integral with the body portion of the rubberheel.

ln order to permit the felt plug to wear evenly, the bottom surface ofthe heel is concaved as at 13 with its edge disposed inV alinement withthe lower surface of the felt plug.

llVith a felt plug having dove-tailed recesses along its edges, thetendency of the felt to separate from the rubber' is avoided as it isimpossible for the dove-tail tongues of the rubber to pull out of thedove-tailed recesses in the edge of felt plug during the frictionalengagement of the lower surface of the felt plugwith the ground.

Embedded in the rubber 'portion of the heel is a plurality of metallicwashers let through which openings 15 in the rubber heel is driven theusual securing nails not shown.

With this invention fully set forth it is manifest that a rubber heel isproduced which will prevent the slipping of an individual having thesame secured to his shoes and through the wearing qualities of thematerial involved the expense of repairs will be reduced to a minimum.

Having thus described this invention what l claim is:

A cushion heel for shoes comprising an elastic body having a concaveinner surface, whereby to create a suction on the bottom of the shoe anda similar formed surface of a greater depth communicating therewith, afelt plug dove-tailed into the lower portion of said heel the lowersurface of which is disposed in a plane substantially in alinement withthe lower edge of said heel, said felt plug being provided along itsedges with inwardly directed recesses which have theirI innerl walls .ofarcual formation the side walls extending obliquely inward to formdove-tail pockets, tongues forming part of the heel held in saidpockets, the bottom surface of said heel being concaved with its edgedisposed in alinement with the lower surface of said plug which has anaperture formed in its central portion, a lug formed integral with thebody portion of said heel held in said aperture, and a plurality ofwashers embedded in said heel with openings communicating with theopenings in said heel, whereby nails may be driven through said openingsto hold said heel to its shoe.

In testimony whereof I aiiix my signature.

GEORGE F. WELLS.
